Crush Injury

TL;DR

Damage from a heavy object compressing body parts, often leading to serious complications.

What is Crush Injury?

A crush injury occurs when a body part is subjected to a high degree of pressure, usually after being squeezed between two heavy objects. This type of injury can lead to significant damage to muscles, nerves, blood vessels, and bones. Symptoms may include severe pain, swelling, bruising, bleeding, and in severe cases, the loss of function in the affected area.

Crush injuries are common in industrial accidents, natural disasters, and vehicular accidents. Immediate first aid is crucial and involves ensuring the safety of the scene, calling for emergency help, and, if possible, carefully removing the pressure from the injured area.

Once the pressure is removed, it is essential to monitor the casualty for signs of shock, which can include rapid heartbeat, clammy skin, and weakness. Applying a sterile dressing to any open wounds and immobilising the affected area can help prevent further injury.

In severe cases, crush syndrome may develop, a potentially life-threatening condition caused by the release of toxins from the crushed muscles into the bloodstream once the pressure is released. This condition requires prompt medical treatment to manage the resulting complications, such as kidney failure and cardiac arrest.

First Aid for Crush Injury

• Call for Help: Dial emergency services immediately.
• Stop the Bleeding: Apply direct pressure to control bleeding.
• Immobilise: Stabilise the affected area to prevent further injury.
• Monitor for Shock: Keep the casualty warm and monitor their condition.

Takeaway to remember

A crush injury occurs when a body part is subjected to significant force or pressure, often leading to damage to muscles, bones, and tissues.
